Driveways Question

Can you block pav over slabs

my front garden is 10mx9m approximatly. half of it is sloping toward my front door the difference from the kerb to my door step is 12 inches, at present there are concrete slabs mainly broken ones,

as they are well compacted can i pav over the slabs?
i need to build a retaing wall and have soil from my garage im building perhaps i can use this to level the drive and then compact 100mm MOT and they lay the paving in the usual way

to aid drainage shall i leave holes at the bottom of the retaing wall?

your suggestions will be most appreciated.

im afraid all this sounds like you want to do a cheap job,do not use dug soil as a base for a drive ,it will sink ,if you want to do it properly ,dig footings for retaining wall ,pour concrete and build retaining wall from desired bricks ,lay membrane to new drive area and fill and compact with good clean h/core ,top off with 100mm type1 mot ,sharp sand screeded to level and lay blocks ,if you require drainage install an aco channel full width and connect to storm run,thats the proper way but like everything thats done right it will cost more ,this will last ,cheap option will start failing/sinking straight away ,

I would agree with everything here except the membrane. Membrane is not required if sufficient type 1 is used there is no way weeds will come through and you are not starting from a wet clay base.
